Our experience reflected others that I've seen in other articles and posts around the world:

They say they're from somewhere like 'Computer Solutions at Microsoft"

They tell you something along the lines of 'Your computer has been experiencing issues that we're here to help you with ... you may have noticed your computer has been running slowly" etc.

They get you to go to the 'run' dialog and run the Event Viewer

They get you to scroll through and find errors and tell you that's a result of the issues (they're just normal errors that don't particularly need attention)

This next part we didn't get to but according to articles: They convince you your system is having problems and so you'll need to head to a website to download the tools to fix it.

They have been known to ask for a credit card payment for around $150 AND you have to enter a code onto their website.

Entering the code and doing a few other things basically gives them remote access of your computer - they now have your money AND can do anything they like with your system, e.g. install keyboard trackers etc.

I had to look at the Application log in Event viewer and all my "Information" items are apparently indicative of infections! Then I had to run "inf virus" which, obviously, opens "C:\WINDOWS\inf" - another source of infections! Next up was to run "iexplore www.logmein123.com" which is when I made up a story about my internet being down for the next half an hour and could he call me back.

It's easy to see how people would get sucked in though. Why wouldn't you trust a random person that rings you up out of the blue?

They (a nice indian guy called Joshua) rang me back and I informed him that I was aware it was a scam but he couldn't understand why I would say that. I reasoned that it was because they lie to people who don't know any better that their computer has things wrong with it when it doesn't. He said they provide a service and 90% of people are happy with it. Anyway, I said it was illegal in my country (is it? I can't see how it wouldn't be) and I was going to report them to the authorities and could I talk to his supervisor.

It seemed that Joshua came back on the line, trying to disguise his voice, as Mr Allen Rosemary (WTF?). He gave me details about the compnay and handed me back to Joshua. It all got a bit surreal to be honest. They didn't try particularly hard to get off the phone with me, I think I could've kept them talking for ages. What's the deal? I'd have thought once they figured out that there was no sale to be made here, they'd move on as quickly as possible and not waste their time/money.

Got one of these calls an hour a go, the demanding asian caller claimed he was from the computer maintenance program and he was receiving unwanted emails from my computer. Alarm bells rang so I hung up.

I got a call the other day from an Indian-sounding lady who said she was from the "Computer Servicing & Maintenance Department" calling about there being "corrupting in the Windows Operating Systems these days". I replied abruptly and hung-up.

A mate of mine said when he got his call he told them that he was software developer and they hung up on him.
